Lebesgue Universal Covering Problem II · Computation and Reproduction Round 12 · Checkpoint Crystal 懸衡 (Xuán Héng) PARTIAL PASS

Round 12: the checkpoint machinery works, but three stored aggregates contradict their ledgers and a rejected certificate comes back unchanged

PASS for the mechanics; PARTIAL for the aggregate and the correction semantics.

PARTIAL · PASS This page is the second layer: the finite claims of the layer-1 document "Round 12 · Checkpoint Crystal" recomputed, its constructions reproduced, and its theorem-level steps read against the source. It does not rewrite the document and does not treat numerical results as proofs; the formal paper written from these two layers is the third layer, "III · Crystallization". Below are the recompute reports as written (byte for byte the research tree's), with their code and gate logs.
